I have a ASUS RT-56U and I have been meaning to set up parental controls on it for some time. Looking through the settings I can see there is a URL filter... is there somewhere I can get a comprehensive list of URLs to add?
I'm using an RT66 so it may not be the same, but you don't have to enter a full url into the filter. It will block any url containing the character string you give it.
You need to be careful though- putting "sex" in there would block you from a lot of Home Counties sites
If you feel like trying it, be aware that enabling the url filter for the first time causes the router to re-boot, so make sure you're not streaming, downloading, transferring files over the LAN etc. It doesn't re-boot when you add a url to the list though.
